The plugs and the mouse could be disassembled to their plastic-only components for 'pickling', yes.

Alas to remove the major component of the yellowed shower-control would involve deplumbing, and removing some tiles/grout where the unit is recessed into the tiles in order to access some of the mounting screws. After going to such a rigmarole rather than trying to clean-up the old discoloured assemblies it's easier to just replace the lot and then I know the job's a good'un for the *next* 15 years.
Seems I can get a chromed-brass unit as a replacement for the plastic one. That shouldn't go yellow!
